Let's say we have an ETH trading exchange where we employ BIP32/BIP44 to generate a unique wallet address for each user. For simplicity, each user uses the same wallet address
(unique to each user) ...

In the BIP by Pieter Wuille it is told that the key prefixed version of Schnorr signature is needed when the scheme is used in combination with BIP32's unhardened derivation. Could someone provide an ...

Not sure if this is the correct forum to ask, but I couldn't find a general one for all cryptocurrencies
I wanted to get an idea on how the whole cold-storage private/public key generation works for ...

BIP 32 allows me to derive keys based off a root key pair, and all these keys will be on the secp256k1 curve. That means I'll be able to use BIP 32 for other coins that are also based on your curve.
...

The below is the snippet from bip-32. I do not understand under what circumstance would 'parent extended public key' be exposed? In the case of e-commerce a 'child extended public key' is derived from ...

i'm trying to derive HD address of bitcoin using Golang. I have extended private/public key. The problem is i'm unable to find any library in Golang that can generate/derive address from the xpubkey/...

So I really have 2 problems now:
I took xpub address for Dash from trezor and used it with blockcypher API to generate addresses with paths like m/0, m/1, etc
I sent some money to that addresses and ...

There is a list of bip44 identifiers for altcoins here.
It uses the term registered coin types. My question is, is there anything in code for each coin that the bip44 number is derived from, or this ...

I' m still trying to grasp the conventions used in HD wallets, so I have a couple of questions:
What's the difference between CKDpub and CKDpriv from the path notation.
What I know is the path just ...

I was trying to understand the specs on CKD function from both the bip32 standard and Mastering Bitcoin book, I couldn't understand how a private key is derived from the left side of the extended key.
...

Instead of using bip32 or bip44 paths what if I use a custom derivation path,
For example: m/0/0/55/1/1/0
I am thinking even if the private key is exposed then can someone guess the derivation path ?...

I was looking through some code for HD Wallets and I saw that they used curve param.N which is specific for whichever curve is used.
Does this mean that when using HD Wallets to derive Private keys, ...

I set up this wallet on the same machine online. Thinking that was it, it was only until i sent funds to this wallet and tried to spend them that i could only partially sign the transaction.
I opened ...

As I understand for BIP32. There are 2048 words.
12 words would give you 2048^12 combinations. However, not all combinations are valid because of the checksum, so how do i calculate the actual space?...

When the Master Private Key and the Master Public Key are generated, can I disclose the chain code as say BIP32? If not, how can is possible verify a child public key with public parameters?
This is ...

I sent funds to a derived address, but I didn't know about the gap limit and how the addresses should be used incrementally. I've used a huge value for the index but wallets only check the first few ...

i am working on a wallet that is using BIP32 for creating Accounts, addresses, xpub, public keys, transaction and etc. but now i want to switch from BIP32 to BIP 44. how can i do this using bitcoinj i ...

Can we please clarify if there is any difference (because apparently some technical documentation explicitly requests to include apostrophes) between a derivation from extended private key (xprv) or ...

Since BIP32 child keys are derived from a master xpub key, and child addresses are the pubkey hash of the child private keys, so is it possible/anyway to correlate that two address are derived from ...

I got locked out of my Ledger Nano S. When setting up the device I was given a 24 words seed passphrase, which I wrote down. The device asked me to verify 3 of the 24 words and my input was valid.
It ...
